HAIR CLIPPER AND SHEARS.

SPECIFICATION forming part of Letters Patent N 0. 478,461, dated July 5, 1892.

Application filed April 2, 1892- Serial No. 427,508. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH K. PRIEST, a citizen of the United States, residing at Nashua, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Hair Clippers and Shears; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to hair-clippers for barbers use; and it consists in constructing the handle which vibrates the movable cutter with an arched portion between its. front operating-toe and the rear shoulder against which one end of the spring bears and having pendent from it a hollow cylindrical bearing through which passes a shouldered hollow cylindrical axle-bearing connection of the stationary handle, and passing through the comb-plate of both bearings and into a spring presslu'e-regulating nut isa coupling tensionbolt, as will be hereinafter described.

The object of my invention is, while greatly simplifying and increasing the durability of hair-clippers, to afford room between the movable handle and between it and the combplate for the location of the spring by which the cutter is enabled to shear or clip the hair on the return-stroke of the movable handle, and by so locating it render the clipper more compact and of less height between the spring-pressure-regulating nut and the combplate, and also afford great convenience in applying the spring around the axial portion of the clipper and to the handles, and also equal convenience for the removal of the spring and separation of the parts of the clipper for sharpening the cutter; repairing or putting in a new spring, cleaning, oiling, and other operations, it being simply necessary to remove the nut, bolt, comb, and cutterplates and invert the clipper to have the parts exposed for cleaning or a broken spring removed and a new one inserted in its place.

In the accompanying drawings, Figure l is a vertical central section of my improved clipper; Fig. 2, an inverted plan view, with some of the parts removed; and Fig. 3 a side elevation, with a portion of the housing connected with the stationary handle broken away to expose the arched form of the movable handle and the relation of other parts.

A in the drawings is the comb-plate which passes through the hair, andB the movable cutter-plate which reciprocates on top of it and cuts off the hair by pressing it against the teeth of the'plate A and simultaneously shearing it off. The stationary lever has a hollow crowning-housing which extends over the comb-plate nearly its full width and forward upon the cutter-plate as Well as to or beyond both of its ends-acting at its front edge with a screw-tempered spring-pressure to keep the comb and cutter plates in the nicest relative cutting relation to one another. This housing is also formed with a guideway for the comb-plate, lugs for connecting the comb and the cutter plates, and with stops and notches for the'application of the spiral springD and the movable handle E to the stationary handle, substantially the same as in most clippers of this type, the only changes being such as adapt the new improved parts for use in the clipper. The movable handle E is formed arching or bowing, asindicated at e, and at the front base end of this arched portion the usual cutter-operating toe f is provided, and in rear of this toe at the rear base portion of the arched portion a shoulder g, which acts as a stop and a bearing for one end of the spring, is provided. The housing of the stationary handle, the comb-plate, and the arched portion of the movable handle are provided with coinciding passages, as is indicated at h h 77/ and in the passage 71 a hollow pendent cylindrical bearing m is fitted and secured by rivet or otherwise; or it may be cast upon the movable handle. Through the bearing m another hollow cylindrical bearing n, having a supporting-shoulder n, is passed upward into the passage h of the stationary handle and fastened by riveting or a screw-thread. The construction of the axial portion might be modified in many .ways without changing the principle of my invention. For instance, a separate revolving holder or sleeve might carry the spring outside of the axial bearing or journal. On the axial \bearing, as described, the spiral spring D,preferably of inverted conical form,

is applied and its ends secured in notches a' a of the handles, as shown, or, as usual, provided said notches are set at such relative attitudes as the new relation of the spring requires. The coupling tension screw-bolt F is formed with a keying-head b on its lower end and a screw-thread on its upper protruding end, and after it is passed through the comb-plate, the cylindrical bearings, and the housing of the stationary handle receives a tension-nutand spring on its screw-threaded end, as shown. This bolt holds the parts together when the clipper is operated in any position and with the nut also enables the required spring-tension to be secured.

By my invention all the parts can be made, arranged, and fitted at the smallest cost, and when the clipper is completed and being used its operation is found very perfect, while the labor of repairing and cleaning is greatly reduced.

What I claim as my invention is 1. In a clipper of the type described, a movable cutter and operating-handle, in combiiiation with a stationary handle and combplate spring connected to said handles and the axial portion of the clipper, said operatinghandle and the other parts named being constructed to allow of the spring being arranged on the said axial portion and below the highest portion of the movable handle in a space between said highest portion of the handle and the comb-plate, whereby compactness is secured and the spring can be removed downwardly when the comb-plate.is removed, substantially as described.

2. In a clipper, the combination of the cutter-operating handle formed with an arched or bowed portion and with a pendent hollow cylindrical bearing, the stationary handle having a housing portion and a hollow shouldered cylindrical bearing projecting from said housing portion and passed through the cylindrical bearing of the movable handle, the coupling and spring-tension key-bolt, the comb-plate, the cutter-plate, anda spring arranged in a space between the arched portion of the movable handle and the uppersurface ot the comb-plate and made removable in a downward direction when the comb-plate is removed, substantially as described.

In testimony whereof I hereunto affix my Signature in presence of two witnesses.
